GEORGE C. BERGLUND, OF CLOQUET, MINNESOTA.

GYMNASIUM APPARATUS.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed May 13, 1907. Serial No. 374,414.

To all whom it may concern:

Be it known that I, GEORGE O. BERGLUND, a citizen of the United States,residing at Cloquet, in the county of Carlton and State of Minnesota,have invented a certain new and useful Gymnasium Apparatus, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to new and useful combination parallel bars, andhorizontal pole, and the object thereof, is to provide a device of thisnature which may be folded or changed as desired.

Furthermore, the invention comprises a pair of standards, each havingT-shaped bases and angularly disposed hinged braces.

The invention aims principally to provide an interchangeable devicewhich is simple and efficient in construction and durable when utilizedin-pract-ice.

\Vith these and other objects in view, the invention comprises furtherfeatures and elements which will be hereinafter described, pointed outin the appended claims, and shown in the accompanying drawings, wherein.i

Figure .l is a perspectiveview of the device illustrating the invention.Fig. 2 is a similar view, illustrating the apparatus adapted as ahorizontal pole, showing the base removed. Fig. 3 is a detail view,illustrating the T-shaped bases for the standards, folded parallel withone of the standards. Fig. 4 is a view showing one of the standards, andits base, before it is completely folded.

Referring to the drawings, 1 and 2 designate a pair of standards Whichare supported in a perpendicular opsition by means of the T-shaped base3, comprising the members 5 and 6, which are hinged to the saidstandards. The members 5 and 6 are braced by the angularly disposedbraces 7, 8 and 9 which are also hinged to the member forming the base,and the upper ends of said braces are provided with angle plates 10, theupper free portions of which are apcrtured to receive bolts .10 whichpass through the said standards. This construction forms a firm base forthe standards and when the upper ends of said braces are detached, fromthe standards, the braces and said base are foldable parallel therewith,as clearly shown in Fig. 3.

The upper ends of the standards are apertured, as shown at 11, for thepurpose of receiving the horizontal bar 12, that is, when the parallelbars are dispensed with,

as shown, in Fig. 2. To securely hold the horizontal bar in place, pins13, are provided, which are inserted at right angles to the plane of theapertures, as illustrated in Fig. 2.

When the device 1s adapted for use as parallel bars, bars 14 and 15 areprovided which are held spaced apart, by means of the lateral braces 16and 17 by means of bolts and nuts 18 as shown. The braces connecting theparallel bars are secured to the standards by means of the bolts 19 and20 and when in this position as shown in Fig. 1, the parallel bars arein readiness for service. From the foregoing it will be clearly observedthat a very ellicient and practical device of this nature is provided,having the parts so arranged, that the device may be changed fromparallel bars to horizontal bars, the difference therein, beingillustrated in Figs. 1 and 2.

Having thus described the invention, what is claimed as new and useful,is:

1. In an apparatus of the class described. a pair of standards. T-shapedbases therefor, hinged angularly disposed brzues for the buses andstandards, and a pair of parallel bars disposed between said standards.

2. In an apparatus of the class described, a pair of standards, T-shapedbases, the parts thereof being hinged to said standards, hingedangular-1y disposed braces for the bases and standards, and a pair ofparallel bars disposed between the standards.

3. In an apparatus of the class described, a pair of standards, T-sbapedbases the parts thereof being hinged to said standards, hingedangulzirly disposed braces for the bases and standards, a pair ofparallel bars disposed between the standards. said parallel bars beingspaced apart by braces, said braces being secured to said standards,substantially as specified.

4. In :in apparatusof the class described, a pair of standards. T-shapcdbases, the parts thereof being hinged to said standards, hingedangular-1y disposed braces for the bases and standards. a pair ofparallel bars disposed between the standards, and a plurality ofapertures formed in the upper portion ol the said standards to receive ahorizontal bar when the parallel bars are eliminated, and pins forpreventing the displacement thereof.

In testimony whereof hereunto alfix his signature in presence of twowitnesses.
